The problems of using non-renewable energies and the need to look for renewable alternatives, which are less harmful to the environment and important to meet the growing demand for energy, make several countries strive to develop new technologies, through research and studies, with the objective of replacing the use of non-renewable energies, following a new world order that seeks to rethink the ways of obtaining and generating electric energy while preserving the environment. This work presents the ability to generate bioelectricity through sugarcane bagasse and straw, and its potential to guarantee the high efficiency of energy cogeneration in the plants. Sugarcane biomass offers many advantages that contribute to preserving the environment in the future. Energy cogeneration, from bagasse and straw, is a good alternative for the Brazilian energy matrix. There are still other advantages in the use of bagasse for energy generation, such as the addition of low-cost energy to the system, immune to exchange rate variations and oil prices. Bagasse and straw can become even more important components in the Brazilian energy matrix, and the potential for this already exists.

It has been increasingly becoming common, in many interpreting situations between Brazilian Sign Language (Libras) and Portuguese, that the interpreters do not work by themselves. For several reasons, among which dealing with the cognitive burden demanded by the activity, many interpreters have been preferring to work in association with other interpreters (RID, 2007; HOZA, 2010; BRÜCK, 2011; RUSSELL, 2011; COKELY, HAWKINS, 2013, quoted by NOGUEIRA, 2016). While a first interpreter takes the turn (called “interpreter of the turn”), a second one assists the interpreter of the turn as a supporter in different ways (called “supporter interpreter”) (NOGUEIRA, 2016; SANTIAGO, 2017). The purpose of this investigation was to analyze and describe the interaction between the interpreter of the turn and the supporter interpreter in a linguistic interpretation involving Libras and Portuguese. For that, we assume Herbert Clark’s thesis (1996) that the language use is a form of joint action in which the participants engage and coordinate their actions so they concretize a joint project. The interpreters work as participants of the situations they are interpreting and their joint work is the focus of interest in this paper. The corpus of this research was constituted by a videotap of the interpretation of a class in virtual format, in which two interpreters worked as a team. The analysis presented in this paper were made after transcribing the video in ELAN, a transcription software created to work on multimodal data analysis. With this work, we could conclude that, to describe to the interaction in a broader way, we must look beyond the mental processes involving the interaction and observe the gestural and corporal elements in the interaction between the interpreter of the turn and the supporter interpreter.

The insertion of the male figure in the spaces of Early Childhood arises from social transformation, through much struggle by feminist movements in order to deconstruct the sovereign paradigm of the heterosexual and Christian white man who imposes the control of bodies and the performance of genders, therefore, the female is seen to be assigned in submissive functions to men, and in school spaces women are seen as caregivers / mothers while men have positions focused on technologies. The entry of male figures in these spaces considered female enables the debate and research on the gender issue, resulting from the non-acceptance of the Brazilian conservative society and even of conservative political groups in the contemporary scenario.

Frailty is a multidimensional syndrome and a predictor of adverse outcomes in the elderly. The aim of this study was to identify changes in the levels of frailty and its relationship with mortality in the elderly in a context of high social vulnerability. This is a prospective cohort study. Two assessment surveys were carried out: one at the baseline (2015) and another after 36 months (2018) in the municipality of São Carlos - SP. For data collection, we used the Phenotype of Fragility, instruments for sociodemographic characterization, health conditions and mortality. The data were analyzed using the software R version 3.5.3 in R-Studio, in which descriptive analyzes were performed, where the quantitative variables were presented in the form of median and the qualitative variables in the form of absolute frequency. Kruskal-Wallis test was also performed; Equality of proportions test; Multinomial logistic regression; Kaplan-Meier survival analysis and Cox Regression. The project to which this study is linked was authorized by the Ethics Committee of the Federal University of São Carlos and the use of the database was authorized. In the first assessment, in 2015, carried out with 346 elderly people, there was a predominance of female elderly (56.4%) and aged between 60-69 years (53.2%). In the second assessment, in 2018, 223 elderly people were reevaluated, who were mostly female (57.4%) and aged between 70 and 79 years old (44.8%). Among those who died, there was a predominance of elderly men (64.5%) and aged between 70 and 79 years (38.7%). Among the fragile assessed in 2015, 36.8% remained in this condition, while 52.5% returned to pre-fragility and 11.8% became non-fragile. In relation to the pre-fragile, 25.4% became non-fragile, 57.9% remained as pre-fragile and 16.7% became fragile. Among those without fragility, 37.9% remained non-fragile, 58.6% became pre-fragile and 3.4% became fragile. In the first assessment, the male gender and the presence of depressive symptoms were configured as factors associated with pre-frailty and frailty. The age group from 70 to 79 years old, on the other hand, was associated with pre-frailty, while lower education and self-rated health were considered to be conditions associated with frailty. While higher education and better health-related quality of life were predictors of pre-frailty and frailty, respectively. Of the elderly who died, 15.6% were frail, 6.2% pre-frail and 3.4% non-frail. In the survival analysis, he identified a higher proportion of non-frail elderly compared to the frail (p = 0.027), as well as for female (p = 0.038), younger (p = 0.021), physically active (p <0.001), with good and excellent self-perception of health status (p <0.001), without urinary (p = 0.013) and fecal incontinence (p = 0.048) and absence of depressive symptoms (p = 0.043). As for the Cox regression model, it was found that frailty (p = 0.040), male gender (p = 0.030), age over 80 years (p = 0.009) and fecal incontinence (p = 0.020) were predictors for death. In conclusion there were changes in the prevalence of frailty, since in the second assessment the prevalence of frail elderly people decreased. However, most participants remained in a pre-fragile condition. There was also a relationship between frailty and mortality, as this condition being a predictor of death in the elderly in a context of high social vulnerability.

The fermentation process is an important stage in the production of ethanol, however throughout production it can occur contaminations that directly influence the quality and quantity of ethanol produced. The main group of contaminating bacteria in the production of ethanol in fermentation are Lactobacillus, which can compromise the efficiency of the process, making it necessary to use antibiotics. In view of this scenario, the present study aimed to evaluate the use of oregano extract (EO) as a natural antibacterial to control these microorganisms. The oregano extract was produced in the laboratory under sterile conditions 24 hours before use. It was applied in four concentrations, 400, 600, 800 and 1000 ppm. Based on these concentrations, the effect of the extract on contaminating bacteria and yeasts was evaluated, based on the number of initial cells and after the inoculation of the extract, comparing it with the commercial antibiotic used in sugar and alcohol plants. To carry out the study, fermentation took place in six hours. The results revealed that after fermentation the oregano extract showed a control effect on the contaminating bacteria. At the highest concentration tested (1000 ppm), EO reduced approximately 73% of the initial microbial load. In this way the results demonstrated that the oregano extract proved to be promising for the control of contaminating bacteria in the ethanolic fermentation process, as well as not compromising the development of fermentative yeasts.

Introduction: The patient with chronic obstructive pulmonary disease (COPD) often has exacerbations that culminate in hospitalizations. These events add a negative impact to COPD including changes in symptomatology and cardiac autonomic function. There is currently an interest in differentiating these patients into phenotypes using findings or a combination of common characteristics. However, it is not known whether patients who report a greater impact of the disease in this period have a worse profile in cardiac autonomic modulation (CAM). Objectives: To investigate whether in patients with Acute Exacerbation of Chronic Obstructive Pulmonary Disease (EACOPD), the impact of the referred disease influences the CAM. Methods: COPD patients of both sexes who were hospitalized for EADPOC were evaluated. The disease impact was assessed using the COPD Assessment Test (CAT) questionnaire, composed of 8 evaluative items on a scale from 0 to 5 with a final score of 0 to 40 points. The patients were divided into two groups: According to the values obtained in the CAT tool in 1) GCAT 1 (N = 11, patients with CAT≤20) and 2) GCAT 2 (N = 11, patients with CAT> 20). The evaluation of CAM was performed by analyzing the heart rate variability (HRV) considering the linear indications in the time domain (mean HR, mean RR, STDRR, rMSSD, RRtri, TINN) and in the frequency domain (LF, HF and LF/HF); and nonlinear analysis by Poincaré SD1, SD2, ApEn, SampEn, alpha1 and alpha 2) using a 300-point stretch in the heart rate record and RR interval in the dynamic process of HR at rest in patients hospitalized for EADPOC. Results: There were no significant differences between GCAT1 and GCAT2 (comparing HRV indications). There was a significant negative correlation between the SNS index and the CAT score (r =-0.44, p= 0.03). Positive correlations between CAT score and HRV variables: STDRR (r=0.54, p<0.01), RRtri (r=0.42, p=0.04), TINN (r=0.52, p=0.01), SD1 (r=0.50, p=0.01), SD2 (r=0.53, p=0.01). Conclusion: The clinical manifestation phenotypes during exacerbations of COPD do not differentiate the profile of autonomic cardiac modulation, however, it was observed that the greater the clinical impact of the disease, the greater the parasympathetic index and the total cardiac modulation.

The present study aimed to investigate the effect of the alignment or misalignment of transitional and phonotactic probabilities on a task of segmentation and simultaneous mapping across ambiguous trials. Forty individuals participated and they were randomly assigned to two groups. The first group listened to a language with aligned probabilities and the second group listened to the same language, but with misaligned probabilities. The experiment was conducted in the Laboratory of Social Interactions of UFSCar and the tasks were presented on a video monitor and performed with the help of a keyboard connected to the notebook where the program was run. The experiment consisted of computer tasks divided into three phases: familiarization with the language, a segmentation test and a mapping test. After doing the tests, participants answered a questionnaire containing questions about their fluency in other languages. The hypothesis was that the word mapping would facilitate word segmentation regardless of the alignment or misalignment of the two probabilities. The results showed that participants of language 1 were able to extract the words and map them to their referents. Language 3 participants, however, did not segment the words above chance, but were able to map them to their referents. Possibly, misalignment of the probabilities affected the preference in the segmentation test. A next study needs to investigate the segmentation process with L3 in order to explain the results obtained in the present study.

The emergence and formation of species is an area of great interest in the scientific knowledge of genetics, conservation biology and evolution. One of the most validated conceptions in relation to the formation of species is the factor of isolation barriers, in which populations that mate naturally with each other are reproductively isolated from other groups. In this work, a bibliographical survey of the theories involving natural hybridity or interspecific reproduction between animals and consequences for species was carried out. It can be seen that this type of hybridization with the formation of fertile intermediates occurs frequently, and can be observed, for example, in the species of sea turtles Eretmochelys imbricata and Caretta caretta belonging to the Brazilian coast. In addition, from this hybridity they have not shown reproductive differences in relation to their parents and are reported in a relatively high incidence. The same occurs with the species of gulls Laurus glaucescens and L. occidentalis, belonging to a certain hybrid zone of North America, in which it is researched that their specimens of intermediaries will be as fertile as their parents. In other studies, bird species Pyriglena Atra and P. leucoptera that, despite the fertility of their intermediaries, highlighted results that are still inconclusive on the consequences of this reproduction. It was also possible to evaluate researches where hybridism can have negative consequences for the species involved, as occurred with species of marmosets Callithrix sp. found in Brazil where, due to anthropic actions, they shared the same habitat and a reproduction between them generated an ecological disturbance. In this way, the results obtained through the present bibliographic survey demonstrate that it is necessary to reevaluate as assumptions about species from natural hybridity, demystifying the rarity of the event in nature, in order to build a focus on fertility and evolutionary productivity in order to contribute with correlated studies of genetics and evolution of species.

The implementation of digital technologies is a trend that has been growing in the food services sector outside the home in Brazil. In order to understand this scenario, this work aimed to identify and analyze the factors that impact the experience of customers with the use of digital technologies in the food service sector. A quantitative research approach was adopted, in which data were collected through a survey questionnaire. The sample consisted of consumers who have already attended food service establishments that use some of the following self-service technologies: digital menus, available on mobile devices coupled in the center of the table and /or self-service totems. The results showed that most customers had positive experiences with the use of digital technologies in food service, where the factors considered most important in the research were speed and efficiency and ease and simplicity. Despite the positive experiences, the interviewees showed low willingness to face queues or pay more in restaurants that use self-service technologies and, most did not consider fun and pleasure relevant to their experience, making them the least important factors identified in this study. With the realization of this research, it was possible to clarify the impact factors in the consumer experience with technological applications in food service, bringing theoretical contributions, by exploring a topic little addressed in the Brazilian context, and managerial, by serving as a basis for making decisions about the implementation of new digital technologies of self-service, as well as for understanding the preferences and expectations of customers.

It is not new that perfumes are objects of desire for many people, and it is also no accident that the culture of perfumes is very old and still generates many profits. They arose with the main intention of pleasing the Gods in offerings and religious temples, however, due to their great repercussion among citizens during the offerings, tributes and in the temples, they soon started to serve mainly men and women, which enabled a series of advances, and artisanal techniques, which were small in the beginning, in order to extract essential oils and produce perfumes. As our society grows and develops, this production was gradually transferred to large industries, the ones we know today. Through this theme, this work appears as a CTS proposal to the teaching of Chemistry, since the subject of perfumery transcends time, growing and developing socially. For this, the work has the incentive of this CTS perspective to promote interdisciplinarity by relating concepts from different areas, with a focus on chemistry. Therefore, priority was given to the theoretical foundation on the approach itself, the history of perfumery and, finally, materials were proposed to complete the entire experience of this monograph, making relations between the theory and practice of “Chemistry of perfume”.

Chemical transformations promoted by the irradiation of light have aroused the interest of the synthetic community since the beginning of the 20th century. However, due to the lack of appropriate technologies to perform photoinduced transformations, photochemistry and photocatalysis remained in the perception of many chemists as a specialized technique, with few practical applications and on large scale. Currently, with the development of new photochemical methods and the emergence of new technologies that have facilitated access to different sources of irradiation, the interest in investing in photochemical transformations has reappeared in search of more efficient methodologies that employ milder conditions. Thus, in recent years as an alternative to the commonly used photocatalytic methods, organic reactions induced by visible light via the formation of EDA complexes have received great attention due to their synthetic potential to promote a wide variety of chemical transformations involving the formation of carbon-carbon and carbon-heteroatom bonds.

For family farming, the flow of production has been one of the biggest bottlenecks within the productive rural units. Agroforestry systems are becoming a relevant alternative for food production in family farming, but not only, is the commercialization of products from agroforestry also relevant to guarantee the permanence of families in the countryside. This work aimed to characterize the main commercialization channels of family farmers in the state of São Paulo that produce from SAFs and to understand the stimuli and challenges of rural producers, and how they are socially and economically related through agroforestry production and marketing. Through documentary analysis, reports of visits to the properties, semi-structured interviews and free audios collected during visits by Embrapa Meio Ambiente in the SEISAF macro-project during the years 2017 and 2018. As part of the results, 3 experiences with positive perspectives were chosen from individual challenges. The analyzes showed that short sales channels are potent in generating income, in agrobiodiversity, in changing the perception of families in relation to SAFs and the production unit as a whole, in addition to bringing important elements to the issue of commercialization and to strengthening the small-scale ecological-based agriculture.

Changes in land use through deforestation and forest degradation have resulted in great losses of biodiversity and ecosystem functions and services and recognition of the importance of forests has resulted in several actions for their restoration. Plant growth rates can be strongly related to the leaf area per dry mass unit (SLA) which reflects the photosynthetic capacity per leaf area unit. However, other crown attributes such as the projection area of the crown, the surface area of the crown and the number of leaves can contribute to the photosynthetic capacity of the plants and thus influence the growth rates. The objective of this study is to evaluate the influence of SLA and the attributes of the crown on the growth rates of the plants of eleven tropical tree species reintroduced in a degraded area. For each species, five individuals were marked for growth monitoring over a year, measuring the total number of leaves, three crown measures (height, largest diameter of the crown and the orthogonal diameter to the largest diameter). From each individual, two expanded leaves were collected to estimate the SLA. The leaves were photographed, to estimate the leaf area, and weighed (fresh mass), and then left in the greenhouse, to estimate the dry mass. SLA is the ratio of the leaf area to the dry mass. Five models were evaluated to determine the influence of crown attributes on the relationship between SLA and the growth rates in height of the plants: (I) - considering only the SLA; (II) - AMF × SLA; (III) - CPA × SLA; (IV) - CSA × SLA and (V) - SM. The choice of models was made according to the corrected Akaike criterion. Model III, the relationship between RGR and SLA x CPA, was the one that best explained the growth rate of individuals, followed by model IV, showing that the larger the leaf area, the crown projection area and the crown surface area, the higher the relative growth rate of the species. In addition, model V showed that large seed plants produce small CPA and CSA, compromising the RGR.

Microalgae are a natural source of valuable products and have the potential to be applied in several productive sectors. Among the wide range of biomolecules that synthesize, carbohydrates, proteins and lipids, including carotenoids, are important in health human. Allied to the potentiality of microalgae as biomolecule producers, we have to its production can occur in areas that do not compete with food production and yet, as photosynthetic beings that are, fix CO2, a greenhouse gas. Given the plasticity physiological of the microalgae, techniques of manipulation of its biochemical composition have been proposals for the increase of biomolecules. In this study we investigated the physiology of microalgae Kirchneriella contorta under different concentrations of copper and in two colors of light (diodes light emitters - LED), red and blue. In a first step, under white light we define a range of copper concentration that would not cause a change in the growth rate and in the second stage, crops grown in these concentrations were exposed to white light (control), blue and red. The population density and rates of growth, photosynthetic parameters (PhytoPAM) and concentration of chlorophyll biomolecules a, carotenoids, proteins and carbohydrates. The results showed that the photosynthetic apparatus was sensitive to changes in the quality of light and the presence of copper. From 1.4x10-8 mol L-1 of Cu2+ there was an increase in non photochemical NPQ dissipation, which led to the overcoming of stress, keeping photosynthetic yields similar to control. Chlorophylls biomolecules a and b, carbohydrates and proteins showed higher productivity in intermediate concentrations of copper in the first 48 h of cultivation under white light. Under light blue and at a concentration of 3.8x10-9 mol L-1 of Cu2+ free there was an increase of 50% in the productivity of carotenoids and carbohydrates and 30% of proteins. Growth rates have always remained similar to control, regardless of light quality or concentration of copper. We have shown that, if supplied in the correct quantity, copper can stimulate productivity of biomolecules, and that this productivity can be magnified by synergism by combination with blue LED. This duo proved to be a great tool for biochemical manipulation and growth of Kirchneriella contorta. This study is a contribution to microalgae biotechnology and understanding of the physiology and effects of copper and blue and red light in the microalgae, K. contorta a fresh water Chlorophyta.

The predation of domestic herds by jaguars (Panthera onca) and pumas (Puma concolor) is a reality in rural areas in several properties, including in the quilombola remnants of Vale do Ribeira. This fact generates high economic losses at the place and ends up being one of the reasons for these species to be pursued and hunted. As a result, the negative feeling about the jaguars and the persecution of them intensifies, which makes conservationist actions difficult to protect these great predators. Therefore, the present work investigated, from a qualitative analysis of the bibliographic review and semi-structured characteristics, in relation to the conflict between the big cats and the quilombola communities of Vale do Ribeira. The survey of the discussion brought different aspects that encompass the theme of human-fauna conflicts. The main points were as perceptions about this fauna group, which, mostly negative; as possible measures and proposals to alleviate the conflict; and the importance of having more efficient means for communication between the different agents (researchers, quilombolas and conservation professionals), considering the way of life of these local populations and their historical and cultural dimensions.

This work aims to analyze the panorama of agricultural cooperatives in Brazil and its regions through the following variables: number of agricultural establishments; number of agricultural establishments organized in associations; number of agricultural establishments organized into cooperatives; technical guidance; use of fertilizers and pesticides. The research methodology is quantitative based on the collection and tabular analysis of secondary data present in the IBGE database based on data from the Agricultural Census of 2006 and 2017, where it was found that the regions that are most associated with cooperatives are the South, Southeast and Midwest regions and, consequently, are the ones that most benefit from this association. The Northeast and North regions, on the other hand, are those that least associate with cooperatives and those that least benefit from cooperatives. The data pointed out the need for incentives for the Northeast and North regions to associate more closely with cooperatives in order to strengthen agriculture in these regions. In addition, it was possible to observe a strong relationship between cooperatives and technical assistance, considering that the regions that most associated themselves with cooperatives were also the ones that received the most technical guidance and, consequently, those that used fertilizers and pesticides the most.

The virtual channels for sales have become increasingly relevant for customers and companies. In this regard, the global coronavirus pandemic (COVID-19) situation during the year 2020 has led to significant changes in consumption habits, in particular, the migration to shopping in the online world. Thus, it is important to understand the aspects that affect purchase decisions in virtual stores. The objective of this research was to verify the factors that influence Brazilian consumers' online purchasing decisions and to analyze the impacts of the pandemic on online shopping behavior. To achieve this, a quantitative approach was adopted, through the application of a survey. The results found concern to the behavior of the customers of virtual stores, as well as their expectations and perceptions. From the study, it was found that among the main factors in the purchase decision on the virtual channel are ‘trust in the store’ and ‘product/service quality’. Regarding the impacts of the pandemic, there was an increase in the frequency of purchases through the internet and some changes in consumer behavior. Therefore, this work adds to the literature findings on the most relevant factors in the online purchase decision of Brazilian consumers, as well as reflections on changes in online shopping behavior during the pandemic period. In addition, it provides insights to managers for strategic decisions related to the digital market, both for those who want to enter the online channel and for companies already present in the digital world that need to understand their audience to properly adapt their online strategy.

The research’s goal is to analyze AIESEC’s organizational culture, an International Non-Governmental Organization (INGO) formed by students between 18 and 30 years old. The methodological approach used is based on interviews with members, documentary research, informal conversations with active and inactive members and visit to the physical space. The collected information is organized mainly following the proposal of two authors: Fleury (2012) and Schein (2004). It is possible to observe that issues connected to both Assumptions About External Adaptation Issues and Managing Internal Integration are well defined and broadcast throughout AIESEC. Besides that, by the perspective adopted by Cameron and Quinn (2006), the organization embraces several characteristics associated to the type of organization called “Clan”, however, it also has characteristics assigned to other types of organization. Lastly, it is notable that the organization presents characteristics identified by Boli and Thomas (1997) as typical of INGOs. However, the lack of references about the topic narrow a further research about it.
